What is meta-externalads?
meta-externalads is a web crawler operated by Meta that scans websites to gather information about content that may be shared or advertised on Facebook's platform.

Frequently Asked Questions
What Traffic Patterns Should I Expect From meta-externalads?
meta-externalads's traffic pattern depends on the intelligence being collected. It may revisit specific pages on a schedule, crawl broader sections of your site, or appear only when information is requested. Its request scope and frequency reflect the underlying objective.
Does meta-externalads Follow Robots.txt Rules?
meta-externalads is expected to follow robots.txt rules, so a disallow rule is the appropriate first step if you want to block it. Automatic Robots.txt can add and maintain that rule, while Agent Analytics lets you verify whether meta-externalads respects it.
Is meta-externalads Used for AI Model Training?
Possibly, but its category does not establish that purpose. meta-externalads's operator may use or provide the collected content for AI training or for unrelated automated tasks.
Does Blocking meta-externalads Affect AI Search or Citations?
Not directly. meta-externalads's expected purpose is not to supply an AI search index or retrieve pages for AI-generated answers.
Does meta-externalads Access Private Content?
No special access. meta-externalads can read publicly available pages but cannot bypass authentication. Assume anything you publish openly may be collected.
How Can I Verify a Request From meta-externalads?
Agent Analytics tracks visits from meta-externalads and every other known AI agent, crawler, and scraper, then authenticates each visit using meta-externalads's published verification method. You can also check your server logs for requests whose user-agent string contains "meta-externalads". Traffic may range from repeated requests to the same pages to broader crawls or one-off fetches. A matching log entry alone is not proof because any bot can claim to be meta-externalads.
